Hey all having some issues with my current project i have 2 8x8 (4 unit panels) and i have tried using and following the steps to mod the md_72xx.h file to reflect my hardware and i have been looking all over in the files and cannot find the #define hardware  lines to allow me to change it to work.

@laserman

Perhaps you'll understand that it's hard for us to help you when we can't see your code and don't have a description of the error (if any) or the deficiency (if no error).

For instance, what error (if any) are you seeing.

Is the fault at compile time or run time.

What do you expect to happen and what actually happens.

These kind of details are really important.

@laserman Did you mean md_MAX72xx.h?

@laserman If you have only 2 8x8 then the statement is #define MAX_DEVICES 2

A complete solution is at https://dronebotworkshop.com/led-displays/

@laserman Sorry, I don't understand what you are saying. See the help and learn how to post your sketch. Then describe what you thought should happen and what did happen, then maybe somebody can help. All our mind readers are on vacation.
